Emma Watson's British Sign Language For Deaf People

I am deaf and from United States of America, I am alumnus of prestigious university and involved many human rights for my political work for many years. I am aware of Emma Watson who involved UN Human Rights and HeForShe organization, I love to see her working with deaf people who want to participate this.

I am here to ask you question that do Emma Watson know any British Sign Language For Deaf People, no matter if you already met her in person and you may ask Emma Watson if she know any British Sign Language after her meeting with Deaf People or she may be aware of Deaf Culture if she already met Deaf People in the past.

If you are close friend of Emma Watson, Can you ask Emma Watson if she know any British Sign Language? Because I would like to see communicate with deaf people who ask her about her UN and HeForShe work.
